Ivory Coast officials said Kolo Toure contracted malaria after visiting the Ivorian city of Abidjan before joining the squad in Dallas.

The Liverpool defender did not play in the 2-1 friendly loss to Bosnia-Herzegovina on Friday in St Louis, but is expected to recover from the illness this week, according to the Ivory Coast Football Federation.

The federation also said that Yaya Toure joined up with his teammates on Friday after a trip to Qatar and trained on Sunday.

The Manchester City midfielder is one of three players recovering from minor injuries, along with Ya Konan and Bolly.

Ivory Coast, the world's highest-ranked African nation in 21st position, have a final World Cup warm-up game against El Salvador on Wednesday.

The Elephants then face Japan, Colombia and Greece in Group C at the World Cup.
